TIME-LOCK.

SPECIFICATION forming part o Letters Patent No. 333,682, dated January5, 1886.

Application filed May 26, 1884. Serial No. 132,846. (Model.)

To @ZZ whom t 11i/(ty concern:

Be it known that I, CHARLES H. SHAFFER, a citizen of the United States,residing in the citv of Rockford, county of Vinnebago, and

State of Illinois, have invented a new and Auseful Time-Lock, ot' whichthe following is a speciiication.

This invention relates to a locking mechanism in which a tiinevmovementis employed 1o to determine the time at which the lock may be opened.

The object of this invention is to provide a time-lock which while thetime-moveinentis running can only be opened at a predetermined time bythe combination to' which the lock has been adjusted, and when thetimemovement is not running additional movements ot' the lockingmechanism, which can be designated by additional numbers to thecombination, are required to open the lock.

This invention consists in a springactuated device to disarrange theadjusted locking mechanism to prevent opening the lock; in a spring-acluated device controlled by the timemovement to permit the lock to beopened at a predetermined time; in a spring-actuated Idevice to permitthe lock to be opened when the movement is stopped; in mechanism wherebythe time-movement may be adjusted 3o to permit the lock to beopened atany predetermined time; also, in automatic mechanism made adjustable toprevent opening the lock on Sunday,or any one day in seven,and capableof adjustment to permit the lock to be opened any day in the week at anypredetermined time, all of which will be hereinafter more fullydescribed.

l In the accompanying drawings I have represented a timeAlock embodyingmy invention, in which Figure lis a face view of a portion of the innerface ofthe safe-door having applied thereto a time-lock embodying myinvention; Fig. 2, a side elevation of the same. Fig. 3 is a face viewot' the mechanism connecting the time-movement with the lock to disar`"range the adj usted locking mechanism. Fig. 4 is an edge elevation ofthe devices shown in Fig. 3. Fig. 5 is a face view of the mechanismconnecting the time-movement,with the 5o lock to disarrange the adjustedlocking mech- "anism, with the mechanism employed to open the lock whenthe time-movement is stopped added. Figs. 6, 7, and 8 show variousportions of the parts in opening the lock when the time movement isstopped. Fig. 9 is an 55 isometrical representation of thedisengaginglever and its attachments. Fig. 10 is a section of theheplagonal hub and spring to the pintoothed wheel on dotted line x onFig. 2. Fig. ll is a perspective view of a portion of 6o themovement-frame and certain attachments.

The locking mechanism represented in the figures, consisting of thesingle-gated tumblers a a a2 and driving-wheel a3, of disk form,'supported on a suitable spindle, A, 65` within a supporting-frame, B,and mounted upon the door-wall C, including the graduated dial D, thebolt E, and its operating mechauism7 is substantially such as is incommon use in vaults and safes; The time-movement, 7o consisting of thegear-train, balance-wheel, escapement and going springs,supported withinthe frame-work F, is ofa well-known construction. This timemovement ismounted on a p suitable supporting-frame, Gr, iiXed to the v door-wallin such relative position with the locking mechanism that suitabledevices may be employed to connect the time-rnovement with the lockingmechanism. The time-movement is connected with the locking mechan- 8cism by means of a right-angle lever consisting of a rock-shaft, H, avertical lever-arm,

I, and a horizontal lever-arm. J. This rightangled lever is supported bymeans of its rock- Y shaft on pivoted bearings on the frame G 'on 85which the time-movement is supported, and

in such position thereon that thel free end of the vertical arm Iextends nearly to the locktumblers, and the free end of the horizontalarm J extends forward of the face side of the 9o movement-frame.

At bis represented a lever having a free pivotal connection with thefree end ot' the arm I of the angle-lever,in such position thereon thatits free upper end will overlap the'95 lock-tumbler a.

At c is represented a spring having a pivotal connection with the lowerend ol' the lever b. This spring c, from itsconnection with the lever b,depends in a plane substantially roo parallel with the lever-arm I, andits depending end is connected to a screwbar, d, made wheel produced indisk,form, having a portion of its periphery cut away, as shown in Fig.3. This drop-wheel is mounted to revolve on the axial center of thecenter shaft of the time-movement, preferably between the facedial ofthemovement and the movement-supporting frame, and it is connected withthe movement by a suitable gear-train in such a manner as to make onecomplete revolution in each twenty-four hours. Itis also made adjustableindependent of the time or face movement, to set the drop-notch in itsperiphery to any time within the twenty-four hours.

At e is represented a drop-lever having one end pivoted at e2 to themovement-supporting frame, said lever adapted to vibrate in a verticalplane parallel with the'plane of the dropwheel. This drop-lever, fromits pivotal support, extends laterally over the movement-supportingframe, contiguous to the rear face thereof, and to the upper peripheraledge of the drop-wheel. An anti-friction roller, e3, projects from theouter face of the drop-lever e at a point to engage the drop-wheelcentrally over its support.

At K is represented a connecting-rod Yhaving its upper end pivoted tothe free end of the drop-lever, from which point it depends, passing ina free manner through the free end of the horizontal arm J of theangle-lever. The lower end portion of this connecting-rod isscrew-threaded and provided with a screw-nut, h, made adjustablethereon, to regulate and limit the descent of the rod through the freeend of the horizontal arm of the anglelever.

At hf is represented a spiral spring placed on the depending end portionY of the connect-ing rod, below the horizontal arm J, and madeadjustable to vary its spring force, and. held in its adjusted positionby means ot' the screwnuts h2 and ha. This spring h is employed to holdthe parts with which it is connected in their relative position in suchmanner that when the anti-friction roller e3 is on the periphery of thedrop-wheel the disarranging-lever b will be held in the track of theanti-friction wheel L on the tumbler; and when the anti-friction wheelis under the disarranginglever the spring h will yield and permit theanti-friction roller e3 to rise from the drop-notch in the drop-wheel toits periphery without materially interfering with the running of thetime-movement.

At L is represented an anti-friction wheel fixed to the outer face ofthe tumbler a of the locking mechanism, in such position thereon thatVin the rotations of the tumbler it will` engage the free end of thedisarranging-lever b when it is in the position shown in the solid linesin Figs. 2 and 4, and will pass under the lever b when in the positionof the dotted lines in Fig. 4. By this construction and arrangement, andwith the parts properly ad justed, it will be seen that when theanti-friction roller e3 is supported on the periphery of the drop-wheelthe disarranging-lever b will be in the position shown in the solidlines in Figs. 2 and 4, in the plane in which the antifriction wheel Lis carried in the rotations of the tumbler. Vhen the graduated dialD isrotated to the righthand to adjust thetumblers in the ordinary manner,the anti-friction wheel L will carry the disarranginglever b totheinclined position shown in the dotted lines'in Fig. 3; and when thefirst tumbler, cI/,is released, by turning the graduated dial to theleft hand to adj ust the second tu mbler, a', the disarranging-lever, bymeans of its spring action, will return to its vertical position, asshown in the solid lines, and in this return movement will carry thetumbler a to its position in the solid lines, and place the gatingtherein at a point distant from the bolt. Thereverse movement of thegraduated dial D, for the purpose of adjusting the tumblers, willproduce like reverse movements of the parts, and in both instances willprevent the adjustment of the locking mechanism, and consequentlyprevent opening the lock. When the drop-Wheel e has been carried by thetime-movement to the position to permit the anti-friction roller e3 todrop into the dropnotch in the wheel,

IOO

as'shown inthe dotted lines in Fig. 3, the

drop-lever e', connecting-rod K, horizontal arm J, vertical arn l, anddisarranging-lever b will be carried by the action of the disarrangingspring c to their respective dottedline positions, as shown in Fig. 4L,and permit the adjustment of the locking mechanism to open the lock.

At M is represented a time-dial of annular disk-ring form` graduatedinto twenty-four, equal'hour divisions, numbered consecutively from oneto twenty-four. This dial M -is mounted over the movementsupportingframe, concentric with the center shalt of the movement on suitablesupports rising fromV the movement-frame.

At Nis represented a rotary dial, made part of or fixed to the dropwheel e, concentric therewith, and to rotate with the drop wheel on thesame axial center. This rotary dial is graduated into twenty -four equalhour divisons, numbered consecutively from one to twenty-four, toYcorrespond with the hourdivisions of the time-dial.

At i is represented an hour-hand, having a frictional connection withthe hour gear-Wheel of the tace-movement, in such a manner as to revolvewith the gear-wheel once in twentyfour hours, but capable of adjustmentto any point on the dial independent of the wheel.

At '13 is represented a minute-hand fixed to thecenter shaft of themovement to revolve IIO therewith, and to make a complete revolutiononce in each hour. The center shaft is frictionally connected with thetime-movement to permit the minute-hand to be adjusted to any point uponthe dial independent of the movement.

From the foregoing it will be seen that the construction and arrangementof these parts are such that the hands may be adjusted to the divisionsof time, and that the dropwheel may be adjusted to permit the lock to beopened at any predetermined time within the twenty-four hours. Thisadjustment of the drop-wheel is accomplished by turning the r 5 rotarydial to the right hand until the hourhand is directly over the number onthe dial indicating the hour or time fixed upon to open the lock.

At 7c is represented a pin -toothed wheel of disk form irregular inoutline, having a peripheral enlargement, 7c. This wheel is fitted withseven pin teeth, k2, projecting from its side at equal intervals, and ismounted to revolve on a stud-journal, and in such relative position withthe rotary dial N that a pin-tooth, k3, projecting from its peripherywill engage one of the pin-teeth 7a2 of disk-wheel lc in eachrevolution, and carry the wheel one-seventh of a revolution, or willcause it to make one complete revolution in seven days. The hub Z of thepin-toothed wheel is of heptagonal form. A spring. l', is employed toengage the sides of the hub to limit the movement of the pin-toothedwheel to one seventh of a coniplete revolution in each completerevolution of the rotary dial. The relative position of the pin-toothedwheel k with the connecting-rod K is such that on one day in seven theperipheral enlargement 7c of the pin-toothed Wheel will be automaticallycarried to the position shown in Fig. l to engage apin-stud, Z, whichprojects from the connecting-rod, and operates to sustain the drop leverand the parts connected therewith in their solid-line position, as shownin Figs. 3 and 4, to carry the antifriction roller over the drop-notchin the dropwheel e, and consequently prevent opening the lock on suchday. The pin-toothed wheelkis made adjustable on itsjournal-support, topermit of an adjustment to bring its peripheral enlargement in positionto engage the stud-pin Z2 of the connecting-rod on any one day of theweek, and when adjusted will be automatic on such day in each week untilchanged or ad- 55 justed to some other day.

At m is represented a spur or saw-toothed pinion mounted upon the end ofthe timemovement pinion-shaft 85, to revolve therewith.

Atm'is represented a trip-lever, pivoted upon a stud, s6, which isattached to the rear side of the upper back bar of the movement-frame,and having a serrated pawl, m, pivoted to its end, and a spring, m3,fixed to the edge of said trip-lever in such position that its free endwill engagethe heel end of the serrated pawl to give it positionrelatively with the trip-lever m in a manner to permit a limitedvibratory movement of the free end of the serrated pawl. This lever mf,with the serrated pawl connect- 7o ed therewith, is centrally pivoted tothe movement-frame in such relative position with the spur-pinion m thatwhen the lever is in the position shown in Figs. 5 and 7 the serratedsurface of the spring-actuated pawl m2 will engage the spur-toothedpinion m.

m4 represents a spring employed to retain the lever in its position(shown in Figs. 6 and 8) disengaged from the spur-pinion.

` At 'it is represented a lever of crank-arm form, having its free enditted with an antifriction roller, n. This crank-arm lever a ispivotally mounted upon a support, u2, projecting from an arm attached toone of the posts ofthe frame-work F, to permit a swinging movement ofits free end, and in such relative position with the spur-pinion m as toengage the free end of the serrated pawl when in its elevated position,as shown in Fig. 5.

-At ai is represented a spring coiled on the support of the crank-armlever n, and connected with the support and with the lever-- arm in sucha manner that its spring action tends to carry the arm against a stop,a4, employed to limit its outward movement. This stop a4 is mounted uponone of the posts which connect the frame-work F with the supportingframeG, as shown in Fig. 2 of the drawings. This crank-arm lever/1t isprovided with a latch-pin, p, extending from its inner face parallelwith its support.

At p is represented a liook-detent having a pivotal connection with thedepending end ot' the disarranging-lever b, and a spring, p2, is fixedto the edge of the disarranging-lever in such position thereon that itsfree end will engage the heel end of the hook-detent to give it positionrelatively with the disarranginglever b, in a manner to permit avibratory movement of its free hook-detent end.

Atp3 is represented a pin-stud projecting from the outer face of thedepending endiof the disarranging-lever b, in position to engage thefree arm of` the trip-lever m', as shown in Fig. 7, to cause theserrated pawl to engage the spur-gear, as shown in Figs. 5 and 7.

From the foregoing it will be seen that if the graduated dial D isrotated to the right hand, to adjust the tumblers of the locking j vmechanism in the usual manner, the trip-lever r2o m will, by means ofthe pin-stud p3, be carried to the position shown in Fig. 7, and theYserrated pawl will have engaged the spurtoothed pinion, and when thetrip-lever m is released from the action of the pin-stud the action ofthe spur-toothed pini-on upon the serrated pawl, if the time-movement isrunning, will immediately return the triplever to the position shown inFigs. 6 and 8, and the disarranging-lever will be free to prevent theadjustment of the locking mechanism, as hereinbefore described. It',however, the time-movement is stopped from any cause at any other timethan the predeter- ICO IIO

mined time to which the mechanism has been adj usted for opening thelock, it may be opened by first turning the graduated. dial D to theright a sufficient number of times to cause the serrated pawl m2 toengage the spurpinion m. at Which time the parts will be in the positionshown in Fig. 7, and the triplever will be held in its position by thecontact of the serrated pawl with the spur-pinion. The graduated dial Dis then turned to the lett a sufficient number of times to carry thetumbler a to the position shown in the dotted lines at Fig. 5, whichWill engage the latchpin p and hold the disarranging-lever, to permitthe adjustment of the tumbler a by the first number of the combinationto the position shown in the solid lines in Fig. 5, and the remainingtumblers in the order of the combination-numbers to receive the bolt Fin the gatings ofthe tumblers to open the lock.

For the purpose of more readily openingA the lock when the movement isnot running, theadditional portions of the graduated dial D may bedesignated by additional numbers preceding the numbers employed in thecombination for opening the lock when the movement is running,and forgreater security the additional prefixed numbers to the combination maybe employed as a secret number or numbers known to a single party to becalled upon when from any cause the time-movement has stopped at anytime other than that predetermined at Which to open the lock.

It will be noticed in the drawings that the corners at the upper end ofthe disarranginglever are beveled. This is to obviate the danger ofbreaking by suddenly turning the tumbler back sharply after it haspassed thelever, and the latter is momentarily held in position turnedto'one side. If the corners were perfectly straight and angular, itmight be possible to catch the lever upon its end in such a Way as tobreak or disarrange the parts, so as to destroy the utility of thedisarranging mechanism. If the corners are rounded, it Will of coursehave the same effect as the bevels. rlhe anti-friction Wheel on thetumbler also aids in this direction, as Well as to relieve the frictionand cause the parts to Work more easily in the normal operationexplained y. above.
